<ul>A URL may be attached to a set of geometric primitives that you do
not want to be drawn on the screen, but that you want the user to be able
to select. The "Set Visibility" attribute allows you to disable the rendering
of subsequent geometric primitives.</ul>
<font face="Arial Black"><font size=-1>Notes</font></font>
<ul>For information on additional control over the visibility of geometric
primitives, see the <b>Set Layer</b> opcode.</ul>
<font face="Arial Black"><font size=-1>Default</font></font>
<ul>By default the "visibility" attribute is "on" such that primitives
are rendered, which is the equivalent of executing the following opcode:
<ul><font face="Courier New"><font size=-1>V</font></font></ul>
</ul>
